当我输入syncdb或runserver命令时，错误如下所示。 ＆＃34; TypeError：只能将元组（不是＆＃34; list＆＃34;）连接到元组＆＃34;

如果您使用get_core_apps()，则需要将INSTALLED_APPS列为一个列表，而不是元组。

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.contrib.sites',
    'django.contrib.flatpages',
    'south',
    'compressor',
] + get_core_apps()
